Genes drive them mad.

The scourge of modern society – road rage – is partly the fault of bad parenting, Norwich Union’s (NU) latest groundbreaking motor research has revealed.

Two in five young drivers blame their parents for their erratic driving behaviour, saying they inherited their road rage tendencies from seeing mum or dad lose control behind the wheel.

But fathers are 10% more likely to be blamed, the research said, with two in three men being prone to momentary lapses of decency while driving.

Unfortunately women are twice as likely to panic and lose concentration if seized by the condition.

Curiously, only one in six older drivers (aged 60+) said they were affected by road rage; although one in five were already too angry “with what the world is coming to” to answer the question, unconfirmed reports said.

In the wake of the news, NU linked up with to come up with some top tips, which include: listening to “nice music”; avoiding honking (it can be perceived as very aggressive, apparently); allotting enough time to get from A to B; and the infuriatingly obvious – avoiding “ranting and swearing at other drivers”.
